For me the problem is not that they bend and break, but that they melt! See: http://www.google.com/search?q=magsafe+melted http://www.google.com/search?q=magsaf

See: http://www.google.com/search?q=magsafe+melted http://www.google.com/search?q=magsafe+melted But before I go into this, let me explain the engineering of a power cable. If you look at a power adapter cable for any non-Apple product, you'll notice some metal "spikes" where the plug transitions to the cable. These spikes are called a heat sink. The purpose of a heat sink is to prevent the cable from heating to a severe degree if you use the charger for an extended period. The heat sink allows the cable to have a nice dissipation of heat instead of heating up and melting.
